This invention device.

6 Claims. (01. 93-36) relates to an improved pasting One of the objectsof the invention is to provide an improved pasting device.

Another. object of the invention'is to provide an improved pastingdevice folding and sealing the ends ingcases adapted for pasting. offiber board pack- The device of the present "for pasting, folding, andfiber board packing cases, type of packing case invention is adaptedsealing the ends of more especially the formed of one piece, comprisingside walls. and end flaps extensible from each of the side walls.Usually the end flaps of opposing walls of when folded over, form anpacking cases of this character,

end closure approximately half of the folded length, the end flapsstood, however, that invention is adaptable to packing cases having endflaps of greater or less extension andthat the end flaps just describedshall be considered as illustrative only and not as the invention.

limiting the scope of Reference is had to the drawings in which likeFigure l is a perspective view illustrating a in accordance with planview of the device shown in Figure 3 is a sectional view takensubstantially on the line 3-8 of Figure 2.

Figure 4 is a sectional view taken substantially on the line 6-4 ofFigure 2 In the drawings the device of the present invention is shownmountedupon suitable framework comprising horizontal 2, 4, 5 and 6mounted upon cross members i, -2, standards 1, suitably braced by crossangles, such as 6.

Paste reservoir 9, comprising a substantially rectangular trough isrigidly secured between cross member 3 and riser Iii, the riser It beingrigidly secured to cross-angle Ii.

supplied to reservoir 9 from supply tank l2 through line H. Supply tank82 is rigidly secured to cross member 3, as by bracket M. In the deviceillustrated in the drawings the supply oi paste to reservoir 9 isthrough the medium of hen manually controlled d valve 45. it will b Trayor apron 22 may be provided beneath reservoir 9 to catch fragments anddripplngs of paste. Ledge 22, reinforced by web 24, is welded orotherwise rigidly secured to'riser III, as by arm 25. Ledge 22 isextended forwardly of the forward end 26 of roller I 6 and is securedsubstantially in alignment with the uppermost surface of roller 16.

Baille 21, of substantially semiconical formation, is rigidly secured.-between cross members 6 and 4, below ledge 22 and to either side ofledge 22. Baille 2! commences at a relatively large substantiallysemicircular end 22 and upwardly to a relatively small flatend 29.

Carton blank supply rack 20 provided with rear wall 2| and retainingledge 22 is rigidly secured between cross members 3 and 6 and standards22, 20, and 26. 30

In use an operator standing in the corner defined by cross members 2 and6 lifts one of the supply of carton blanks 26 from rack 20 and pressesit at its folded ends so that the side walls and corresponding end flapsopen to a sub- 85 stantially rectangular formation. The partially formedcarton is then grasped by the operator at approximately the top edge sothat the side walls flaps 2i and 22 are held substantially transverselyof paste roller l6 and the remaining end flaps 39 and 40 are heldsubstantially longitudinally of roller I6. The operator then moves thepartially formed carton blank 26 down onto roller l 6 with a slightlydrawing movement toward the end 26 of roller IS in a manner such thatflap 21 will strike the ungrooved portion of roller l6 and be foldedin-. wardly.

The carton 26 is then given a slight backward movement toward the end 20of roller l6, whence the end flap 28 is seated within one of the grooves2| and is folded inwardly toward the end flap 31. The carton 26 with theend flaps 2! and 38 5d and tapers inwardly 25 each resting against thesurface of roller I6, is then moved from side to side transversely ofroller l6, sufiicient pressure being applied such that roller l6 will berotated and thus apply a film of paste to the contacting surfaces offlaps 31 and 3B.

Carton 36 is then moved toward end 26 of roller l6 and over ledge 23 andonto packing table or conveying means II. In the movement of carton 35over ledge 23 the end flaps 39 and III are moved against baille 21,whence they are folded inwardly and upwardly against the paste coveredsurfaces of end flaps 31 and 38. The end flaps 31 and 38, and 39 and 40are sealed one against the other by pressure applied to the carton as itis moved onto packing table ll.

I claim:

1. In a pasting device, a paste roller, means for applying paste to thesurface of the roller, a ledge secured adjacent one end of the rollerand in substantially longitudinal alignment with the roller and a flapfolding baille mounted below and to either side of the ledge.

2. In a pasting device, a past roller, means for applying paste to thesurface of the roller, a ledge secured adjacent one end of the rollerand in substantially longitudinal alignment with the topmost surface ofthe roller and a substantially semiconical flap folding baille mountedbelow and 'to either side of the ledge.

3. In a device for applying paste to a surface of a foldable flap of acarton, a paste roller provided with a peripheral foldable flap engaginggroove, means for applying paste to the surface of the roller, a ledgesecured adjacent one end of the roller and in substantially longitudinalalignment with the topmost surface of the roller and a substantiallysemiconical flap folding baiiie mounted below and to either side of theledge.

4. In a device for pasting and securing the ends of a carton having fourside .walls and an end flap extensible from each of the side walls, apaste roller adapted for applying a film of paste to the outer surfaceof two of the opposing folded end ilaps, a ledge secured at one end ofthe roller and in substantially longitudinal alignment with the topmostsurface thereof for holding the paste covered end flaps in foldedrelationship, and a substantially semieonical bailie mounted below andto either side of the ledge for folding the remaining opposing end flapsinwardly and upwardly against the paste covered end flaps duringmovement of the carton over the ledge.-

5. In a device for applying paste to a foldable flap of a carton, apaste roller, means for opposing the passage of the edge of the foldableflap along the roller whereby the flap is folded and the surface thereofis caused thereby to come into contact with the surface of the pasteroller, a ledge secured adjacent to one end of the roller and inlongitudinal alignment with the topmost surface of the roller, and asubstantially semiconical shaped flap folding baffle mounted below andto either side of the ledge.

6. In a device for apply paste to a foldable flap of a carton, a pasteroller, means for opposing the passage of the edge of the foldable flapalong the roller whereby the flap is folded and the surface thereof iscaused thereby to come into contact with the surface of the pasteroller, a. ledge secured adjacent one end of the roller and insubstantially longitudinal alignment with the roller and a flap foldingbaiile mounted below and to either side of the ledge.
